SLB-50-500PIR2 50.0 mm Dia. x 500.0 mm FL; Coated; Plano-Convex Lens 750-1550nm

The SLB-50-500PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens boasts a circular base shape, with a diameter of 50.0 mm and a thickness at the edge of 3.0 mm, transitioning to a center thickness of 4.2 mm. The effective focal length (EFL) of this lens is 500.0 mm, with a front radius (R1) of 259.5 mm and a back focal length (BFL) of 497.2 mm.

The lens is crafted from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The front and back surfaces of the lens are coated with Opt IR2, a specialized anti-reflective coating that enhances transmission within the specified wavelength range.

This lens is an excellent choice for applications that require a large focal length and transmission within the near and short-wave infrared spectrum. Its Plano-Convex design allows for efficient light gathering and minimal spherical aberration, making it suitable for a wide range of optical systems.
